A Steady State Analysis of the Adaptive Spectral Line Enhancer.

Abstract

The adaptive Spectral Line Enhancer (SLE) is a device for automatically prewhitening noise with unknown spectrum and extracting (enhancing) spectral components to which the noise is additive. The steady state performance of the SLE is presented for the general case of multiple spectral lines. The theoretical steady state SNR performance of the SLE is shown to be that of a spectrum analyzer with resolution determined by the length of the adaptively weighted tapped delay line which is used to implement the device.
